Go for it now. The future is promised to no one.

To know oneself, one should assert oneself.

If you're going through hell, keep going.

After a storm comes a calm.

Know or listen to those who know.

Be thine own palace, or the world's thy jail.

Never complain and never explain.

Quality is not an act, it is a habit.

The wise does at once what the fool does at last.
